Yes, we would assume here that bacon means pork belly bacon. The reason nitrates are such a big deal with American bacon is that they're an important part of the flavor of the bacon (nitrates create "hammy" flavor). If there's genuinely un-cured pork loin "bacon" in Germany or New Zealand or whatever, that's great, but it's a less interesting claim than that there's real nitrate/nitrite-free American bacon (I don't believe there is).

Sorry my question wasn't about nitrates. It was about the use of the term bacon being used to define all bacon's as we're a global community or whether people in general on this community would think of bacon being used for only streaky bacon.

I totally understand. I know "bacon" is a thing everywhere, and it doesn't mean cured strips of pork belly everywhere. I guess I'd say "bacon" in popular culture refers to the American product, whose flavor is heavily derived from the interaction of sodium nitrite with pork belly. To tell an American "you can get bacon without the nitrites" is a little like saying "you could just go eat an apple". True, but irrelevant! :)
